Probing the realities of anemic tendencies in female students of junior high and high school through the use of the near-infrared spectroscopic imaging method

The purpose of this study is to make clear the realities of blood hemoglobin concentration in female students of junior high and high school with Astrim. The subjects were comprised of 260 female students belonging to one junior high and high school and 33 of their mothers. The investigation was carried out from April to May 2009. The item under investigation was blood hemoglobin concentration, which was measured through using the near-infrared spectroscopic imaging method.The main findings were as follows: 1) The blood hemoglobin concentrations were 13.1±1.5g/dl for junior high school students, and 12.4±1.4g/dl for high school students. The blood hemoglobin concentration for high school students was significantly lower than that of junior high school students(p<0.05). 2) According to the WHO standards, 19.7% of junior high school students, and 36.2% of high school students have anemic tendency. 3) A significant positive correlation was recognized between the blood hemoglobin concentration of high school students and their mothers (r=0.581, p
